| 1 | Pyrolysis of Huadian oil shale by electrical heating on different heating rates显示文摘The electrical heating experiments on oil shale sample from Huadian of Jilin were carried out by the pyrolysis method at three different heating rate 2℃/ min,5℃/ min and 10℃/ min in the temperature range of 30℃-750℃ . Heating rate 2℃/ min is considered low,while intermediate one covers the range 5℃/ min and high heating rate is 10℃/ min. The controlling parameters studied were the final pyrolysis temperature and the influence of the heating rate as well as type. The heating rate has an important effect on the pyrolysis of oil shale and the amount of residual carbon obtained therefore. It is found that increasing the heating rate and pyrolysis temperature also increases the production of oil and the total weight loss. Higher heating rates resulted in higher rates of accumulation. The rate of oil and water collection passed through the maximum of different heating rates at different pyrolysis temperatures. Heating rate affected density,oil conversion and oil yield. | G.Roland Nguimbi | 2012 | Global Geology2012，15，2： | 2 |

| 3 | Interpreting effects of TOC_(inert) organic content on source rock potential using S_2 vs. TOC graph in Maamba Coalfield,southern Zambia显示文摘The authors present the effects of the total organic carbon( TOCinert) during pyrolysis and how it overall affects the estimates of the hydrocarbon index( HI) using the cross plot S2 vs. TOC graph. A total of 21 drillcore samples consisting of the non-carbonaceous mudstones,carbonaceous mudstones,coaly mudstones and coals with S2> 0. 35 are selected and used. The average TOC for the sampled population is 10. 36 wt%.TOCinertmeasured from the S2 vs. TOC graph is 2. 97 wt% and the average pyrolysable TOCliveis 7. 39 wt%. The HI is 102 mg HC / g TOC and the pyrolysable HI is 175 mg HC / g TOC,indicating that the TOCinertor mi-neral matrix adsorbs some of the hydrocarbons liberated during pyrolysis resulting into the low HI values which affects the correct determination of the source rock potential. Other applications of the S2 vs. TOC cross plot have been used to determine the depositional system tracts. The high stand system tract is also determined through this method. | Cryton Phiri WANG Pujun G.Roland Nguimbi Abdallah-Yousif Ibrahim Hassan | 2014 | Global Geology2014，17，4： | 0 |
| 4 | 流的偏心率——在相对论性重离子碰撞过程中初态物质的椭圆流涨落和横向局域化证据(英文)显示文摘Recent measurements of event-by-event elliptic flow in Au+Au collisions at S_(NN)^(1/2)=200GeV exhibit large relative fluctuations of about 40%—50%.The data are well described by fluctuations in the shape of the initial collision region,as estimated event-by-event with the participant eccentricity using Glauber Monte Carlo.These results,combined with the demonstrated participant eccentricity scaling of the elliptic flow across nuclear species,constitute evidence of transverse granularity in the initial matter production in these collisions. | S.Manly B.Alver B.B.Back M.D.Baker M.Ballintijn D.S.Barton R.R.Betts R.Bindel W.Busza Z.Chai V.Chetluru E.Garcfa T.Gburek K.Gulbrandsen J.Hamblen I.Harnarine C.Henderson D.J.Hofman R.S.Hollis R.Hoiynski B.Holzman A.Iordanova J.L.Kane P.Kulinich C.M.Kuo W.Li W.T.Lin C.Loizides S.Manly A.C.Mignerey R.Nouicer A.Olszewski R.Pak C.Reed E.Richardson C.Roland G.Roland J.Sagerer I.Sedykh C.E.Smith M.A.Stankiewicz P.Steinberg G.S.F.Stephans A.Sukhanov A.Szostak M.B.Tonjes A.Trzupek G.J.van Nieuwenhuizen S.S.Vaurynovich R.Verdier G.I.Veres P.Walters E.Wenger D.Willhelm F.L.H.Wolfs B.Wosiek K.Wozniak S.Wyngaardt B.Wyslouch | 2007 | 高能物理与核物理2007，31，12： | 0 |
| 5 | Borehole deviation limits and injection permeability显示文摘Monitoring drilling deviation is important for drilling of boreholes and measuring injection rock permeability by Lugeon value for safe and efficient drilling and grouting. This paper is aiming at the study drilling deviation and relationship between drilling and injection permeability at the depth of 100 m in dam of Pushi River. The results show that at different depths the deviation of grouting borehole is within the allowable range according to specifications. LU value decreases with the depth increased in general, but at the depths between 40-41 m the permeability is 1.5 LU, and at 24 m the LU value is the largest (2 LU) in this site by this study. The study thus concludes that even though the rocks are hard and their injection permeability decreases with depth increased, good drilling practices including carefully considering technical and geological specifications can get good drilling boreholes. | Abdulhakim G.H.Al-Khulaidi SUN Youhong SUN Zhifeng G.Roland Nguimbi | 2013 | Global Geology2013，16，2： | 0 |
